Map between the Management Center client and WebSphere Commerce nouns
The Management Center Web application mediates requests made between the Management Center client and the WebSphere Commerce services by transforming requests and responses.
The Management Center sends URL requests and receives XML-formatted Management Center objects, while the WebSphere Commerce services send and receive BOD messages. The Management Center Web application mediates messages between the Management Center and WebSphere Commerce. Requests made from the Management Center are transformed into the appropriate BOD requests of the WebSphere Commerce service and the responses of those BOD requests are transformed into the XML representation that the Management Center understands.
This diagram illustrates a high-level overview of the Management Center framework, along with the types of requests and responses that are passed between the Management Center and WebSphere Commerce:
The steps required to transform messages differs based on the type of message.
- Retrive Management Center objects by transforming Nouns into XML
When data is sent from the WebSphere Commerce Server to the Management Center, the Management Center Web application transforms Nouns into the XML representation that is expected by the Management Center. The JSP file that represents the Struts action forward is used to transform Nouns into XML format.
- Process Management Center services
Processing Management Center services involves transforming URL requests into Process BODs and Change BODs.
- Manage application errors and system exceptions
The Management Center Web application uses application errors and system exceptions to provide error information.
